This Note is intended to help cricket bat willow growers to identify diseased trees and control the spread of the bacterium in the crop. Introduction I. Watermark disease caused by the bacterium...
The geographical distribution of trees of cricket bat willow (Salix alba var. caerulea) showing watermark symptoms of infection by Erwinia salicis (Day) Chester during 1955 to 1972 is recorded. In an attempt to control the disease by eradication, 23,172 trees were destroyed in this 18-year period, as were 911 mother trees (stools) producing propagating material.
In the U.K. therefore, watermark is recognised primarily as a disease of the cricket bat willow even though it does also affect a wider range of tree willows. Cricket bat willow Wood for cricket bats has to be light, resilient and strong with a straight grain and white colour. All these qualities are possessed by the cricket bat willo (5w. alba var.

The watermark disease is a vascular wilting disease that causes great losses among willow populations. The bacterium Brenneria salicis , formerly Erwinia salicis, is the causal agent of this disease and occurs mainly in the xylem vessels of the host plant. Infected willows show wilted, dried, brown-colored leaves and a watery, transparent color of the wood.

Bamboo cricket bats are stronger, offer a better ‘sweet spot’ and deliver more energy to the ball than those made from traditional willow, tests conducted by the University of Cambridge show. Bamboo could, the study argues, help cricket to expand faster in poorer parts of the world and make the sport more environmentally friendly.
Cricket has been bowled a googly by scientists who have suggested the traditional willow used to make bats could be replaced by bamboo to increase their sustainability and boost the sport’s reach.
